Description

The USB-Ampel is a simple but very effective signal device that is controlled by the PC. It looks like a traffic light with three light areas in red, yellow and green. The light areas consist of seven superbright LED with about 200 mcd each.

The USB-Ampel could also be configred to operate as a watchdog. The name of the device is USB-WatchLight in this case and when started the red light is turned on. In any state only one light is turned on and the two others a turned off. The configuration is done with the device configuration available with ClewareControl.

When a life signal (CalmWatchdog) is received, the green light is turned on. With the life signal, two arguments are supplied to the device. The first argument defines the time after which the red light is turned on. The second argument is the time for the yellow light. In opposite to the other Cleware watchdogs, the times for the USB-WatchLight are defined in seconds.

The size of the device is about 40 x 90 x 23 mm. The valid temperature range for using the USB-Ampel is -20° to +80° C. Using the device outside this range may destroy it. When temperature falls below 0°C, the USB cable should not be dejected to avoid damage of the cable cover.

The usage of the USB-Temp is strictly prohibited when the failure of the sensor will harm people. The usage in medical applications of any kind request the written permission of the Cleware GmbH.

About 32 devices may theoretically be connected to a PC using several HUBs. When using Cleware USB devices it is not neccessary to install device drivers. The standard USB drivers are sufficient. So the system stability will not be harmed.

The USB-Ampel will be delivered with the software ClewareControl for displaying and managing the lights. The software is running with all USB enabled versions of Windows®. (® Microsoft Windows is a registered trademark of the Microsoft Corporation). No special device drivers are neccessary to use the Cleware USB devices. The already installed device driver are sufficient.

The USB-Ampel may also be controlled via the network. The connection is established with the TCP/IP protocol. On the remote control PC the USB-Ampel appears like a local device and could be handled the same way.

An application program interface (API) to drive the USB-Ampel from customer programs is part of the delivery. The API bundles some very simple functions for controlling the device. The complex USB device handling is hided.
Linux support is also available.

Every USB-Ampel own its unique serial number. This make it easy to identify the devices even when the USB plug position changes or new USB devices are connected.
